Clean Land. Clean Water.

Wisconsin

I got curious today, after considering poor Toledo, Ohio’s ongoing battle with Harmful Algae Blooms (HABs) in its Western Lake Erie drinking water source. And so, I posed a question: In OH, and WI, where are the preponderance of HABs? And, accordingly, where is the heaviest dairy production?

At the risk of making you, the reader, dig deep to find the information I gathered, I am going to here and now provide you with links to my reference articles:

And now, the unsurprising results from this search: wherever HABs are most impactful on a large scale (see: Toledo; see: The Green Bay of Lake MI), the largest presence of dairy cows and

milk production are either already dominant within the state (WI) — or are trending heavily in that direction (OH).

If best-practice standards for farmers remain marginally regulated, and farm operation regulations pale in comparison to what is required from municipalities, HABs will become an increasingly regular event with corresponding intensity.

In the discussion of Harmful Algae Blooms (HAB), there is perhaps no better location to reference than Kewaunee County, WI. As has been discussed in a previous CWW article, dairy farming is big business for this county with a population of about 21,000 people.

Really big business.

So much so that dairy cows outnumber the human population almost 4 to 1. That’s right. Nearly 80,000 dairy cattle, in one small WI county … with a vast Lake Michigan shoreline.

Now, if you are thinking that’s alot of cows, you are correct. And it has created a poopy situation which, despite the play on words, is actually incredibly serious.

In this terrific 2015 study conducted by The Socially Responsible Agricultural Project, mounds of empirical evidence supports the need for a better way of managing dairy cow manure. The well contamination is noted — in fact, this study proposed that it is one-half of the wells in the county that are contaminated — as well as the geological makeup of Kewaunee County; the rampant growth of dairy operations, and more.

All of it is useful information. But, for me, the most glaring number is this:

One cow generates at least 18 times the amount of waste as one human. Every day. 24/365.

And, while municipalities go to great lengths to control street runoff, waste from homes, etc., dairy farms have far less regulation and must meet far lower waste-management standards.

Imagine what the sanitation treatment landscape would look like if Kewaunee County held 360,000 people — making it the fourth most populated of Wisconsin’s 72 counties, instead of its current ranking of #52.

Do you see where this is going?

In the race to provide dairy products to a planet full of people, we are clearly trading freshwater for milk. Since it has been estimated that it takes some 40 gallons of fresh water to produce an 8 ounce glass of milk, that is an alarmingly one-sided deal.

Over the past few days. I have been struggling to find a clear explanation for the HAB (Harmful Algae Boom) that has overtaken Silverwood Lake, which is fed by the Mojave River, in Southeast CA. Then I happened upon a part-time resident of Door County, WI — one of the Midwest’s premier vacation spots– who was lamenting to me about the well-known, on-again-off-again HAB issues this beautiful area has experienced.

“We are told that our children can swim in the water,” she said, “and then … they can’t.”

Silverwood Lake is unusual in that it is deep. Almost 170 feet at its deepest. But it is NOT unusual in its vulnerability to the primary factors which explain HAB in water. Always at the forefront is a tributary or land runoff super-loaded with nutrients — primarily phosphorus — pouring into a slow-moving body of water.

In a nice review by real estate agent Adam Gohlke, the dirtiest water is that which contains the most runoff from farms, and municipalities. The cleanest: spring fed lakes, or lakes formed from exceedingly clean runoff (see: Crater Lake, which is considered by some to be the cleanest lake in the world, and has the added advantage of being one of the planet’s deepest lakes as well). These lakes are always self-contained, with no tributaries leading into them. Geneva Lake, Wisconsin’s second deepest at 145 feet, is an example of a self-contained spring-fed lake.

Gohlke’s basic assessment presents facts which are well-known to the professionals with whom I spoke. And that is encouraging.

Bottom line: not all lakes are created equally, and state and national clean water conservation resources must be shifted to those lakes with many tributaries — which invariably possess excessive nutrients and pollutants. For these surface waters, eliminating invasive fish like carp, invasive and damaging plant life, and creating sizable land buffers between fertilized properties and waterways, are all critical steps that must be taken in EVERY instance.
